The Comparative Study

The article describes the metalwork of the Uzuur Gyalan rock burial, popularly known online in 2016 as the «Adidas Mummy». The definitions and chemical composition of the metalware were compared with those of the time in the region. According to the results of the comparative study, the composition of the bronze mirror is very different from other bronze objects. However, bridles, saddle plaques, and ligaments are similar to the main non-ferrous metals in the region, but appear to have local characteristics. Further detailed comparative studies of the chemical composition of non-ferrous metal products in the tenth century are important steps in establishing regional cultural relations.

The effect of macronutrient omission on the growth and volatile chemical composition of Lippia gracilis was evaluated. The “minus one element” technique was employed by using a complete (Hoagland and Arnon, 1950) nutrient solution and solutions with macronutrient omission for N, P, K, Ca, Mg, and S. Macronutrient deficiency significantly influenced L. gracilis growth and volatile chemical composition. Leaf dry weight decreased in order of importance of the macronutrients as follows: Ca = K = N > P > Mg > S. The amount and composition of volatile compounds varied according to macronutrient omission. The major constituents were characterized by p-cymene (ranging from not detected to 43.41%), thymol (3.86% to 7.95%), carvacrol (44.09% to 76.69%), and caryophyllene (0.52% to 6.00%), the contents of which were dependent on the omitted macronutrient. Lack of Ca, Mg, and S increased the contents of cymene and decreased the thymol and carvacrol compared with control. Complete solution and N, P, and K omission retained the same thymol and carvacrol content. In summary, macronutrient availability effectively controlled plant growth and volatile chemical composition of L. gracilis.
